Definitions

  • Adaptation of the air flow in an evaporator to conditions that provide for high efficiency can also be assisted by an internal subdivision by means of intermediate distributors in an evaporator so that humid air and heated raw water mass flow distribute as uniformly as possible over the cross-section of the evaporator.
  • the brine passes each process stage and the concentration is increased stepwise. This process cannot be continued an unlimited number of times, as the concentration approaches the saturation concentration.
  • the saturation concentration increases with increasing temperature. With cooling, the saturation line can be crossed. According to the invention, this crossing, which leads to crystallisation, should not occur within the apparatus, as then crystals grow on surfaces and can block the flow. In this respect, crystallisation can be allowed to occur in the evaporator if the internals of the evaporator are appropriately configured, such as by using brushes or other elastic internals (see Figure 8).
  • the process and apparatus of the present invention can be used for the generation of pure water for households, for example for a desalination system which operates with a solar heater of 100 kWh/day, an efficiency of 7, and which produces approximately 1 cubic meter of water per day.

Abstract

Un procédé de séparation thermique pour la séparation de liquides comprenant : l'humidification de l'air dans un évaporateur par évaporation d'eau pure à partir d'une eau brute chauffée; la condensation de l'eau pure hors de l'air humidifié dans un condenseur, la chaleur de condensation étant utilisée pour préchauffer l'eau brute dans le condenseur; et le chauffage supplémentaire de l'eau brute préchauffée avec un dispositif de chauffage externe pour produire de l'eau brute chauffée où une paroi active réglable séparant l'évaporateur et le condenseur permet le contrôle de l'écoulement d'air entre l'évaporateur et le condenseur.
